Before treatment starts, you will be asked questions about your medical history and about any surgeries you have had. You will have a complete physical exam including blood (around 3 tablespoons) and urine tests. You will have a sample of bone marrow collected to learn if the lymphoma has spread to the bone marrow. To collect a bone marrow sample, an area of the hip or chest bone is numbed with anesthetic and a small amount of bone marrow is withdrawn through a large needle. You will have either a CT scan or a MRI of the neck, chest, abdomen, and pelvis, and you will have a gallium or PET scan. You will be asked about any medications that you are taking, including over-the-counter medications. Women who are able to have children must have a negative blood pregnancy test.
